A fixing member 4 for fixing the member 2 to the outer wall W (see FIGS. 1, 3 and 4).

(First embodiment)
First, a downspout support 1A according to a first embodiment (hereinafter, simply referred to as a first embodiment) to which the present invention is applied will be described. FIG. 1 is a sectional view showing a downspout support 1A.

As shown in FIG. 1, the downspout holding member 10A of the downspout support 1A is a member formed of a synthetic resin material such as vinyl chloride, and is fitted to the outer peripheral surface of the downspout T to attach the downspout T It has an annular band portion 11 to be held, and a fitting tube portion 36 (fitting protrusion) fixed so as to protrude substantially horizontally from the outer peripheral surface of the band portion 11.
The band portion 11 is formed in a substantially circular shape in plan view so as to be fitted along the outer peripheral surface of the downspout T.

The fitting cylinder portion 36 has the first spherical portion 14 and is formed in a cylindrical shape. A first spherical portion 14 formed in a spherical shape is formed on the inner surface on the distal end side of the fitting cylinder portion 36. The first spherical portion 14 forms a spherical seat 38 protruding outward in the radial direction.
The distal end of the fitting cylinder 36 is reduced in diameter. This makes it difficult for the downspout holding member 10A to come into contact with the base 40, the outer wall W, etc. of the mounting member 2 when the downspout holding member 10A rotates about the fitting projection 20 of the mounting member 2, so that the downspout holding member 10A smoothly moves. It becomes pivotable.

The mounting member 2 of the gutter support 1A is a member formed of a synthetic resin material such as vinyl chloride, and has a plate-shaped base 40 mounted on the outer wall W, a shaft 42 protruding from the base 40, And a fitting projection 20 provided at the tip of the shaft 42.
The base 40 is formed so as to be fixed to the outer wall W of the building with the mounting surface 40a in contact with at least a part of the outer wall W. The mounting surface 40 a of the base 40 indicates a plate surface on the back side of the plate surface connected to the shaft 42.

  Here, the fitting cylinder portion 36 of the downspout holding member 10A and the shaft body 42 of the mounting member 2 are referred to as a gutter support shaft O with their respective central axes arranged on a common shaft. In FIG. 1, the base 40 side of the mounting member 2 along the gutter support axis O is referred to as “wall side”, and the opposite side is referred to as “gutter side”. Further, in a plan view viewed from the gutter support axis O, a direction orthogonal to the gutter support axis O is referred to as a “radial direction”.

The fitting projection 20 has a second spherical portion 22 that spherically fits into the first spherical portion 14 of the fitting cylindrical portion 36 of the downspout holding member 10A. In the first embodiment, the fitting convex portion 20 is formed of a sphere, and the second spherical portion 22 has a spherical surface, that is, a convex curved surface 34 formed in a spherical shape.
In the above configuration, the fitting cylindrical portion 36 can be spherically fitted to the fitting convex portion 20 having the convex curved surface 34, and when the spherical fitting is performed, the convex curved surface 34 is formed by the fitting cylindrical portion 36 from the outside in the radial direction. It is surrounded. A spherical seat 38 is fitted on the convex curved surface 34 on the inner surface of the fitting cylinder 36. A portion where the first spherical portion 14 and the second spherical portion 22 do not contact each other, that is, a gap S is formed in the fitting portion 25 between the fitting cylindrical portion 36 and the fitting convex portion 20. The gap S is located on the gutter side with respect to the second spherical portion 22 inside the fitting cylinder portion 36 in the radial direction.
The mounting member 2 is formed with a through hole H passing through the fitting projection 20, the shaft body 42, and the base 40.

  The fixing member 4A of the gutter support 1A is a member such as a screw made of metal such as steel or a rigid material, and is inserted into the through hole H to be fitted with the fitting projection 20, the shaft 42 and the base. It has a screw shaft 28 (shaft portion) penetrating the table 40. One end 28a of the screw shaft 28 is fixed by being inserted into the outer wall W. The width of the other end 28b of the screw shaft 28 is enlarged, and the other end 28b is disposed in the gap S and is locked by the fitting projection 20.

In the present embodiment, the outer peripheral surface 28R of the other end 28b of the screw shaft 28 and the convex curved surface 34 of the mounting member 2 are connected without any step, and have a spherical surface as a whole.
In the above configuration, as shown in FIG. 1, when the fitting cylindrical portion 36 is spherically fitted to the fitting convex portion 20 having the convex curved surface 34, the first spherical portion 14 becomes a spherical surface composed of the outer peripheral surface 28 </ b> R and the convex curved surface 34. , And can be moved widely and smoothly.

FIG. 2 is a perspective view for explaining a method of assembling the downspout support 1A shown in FIG. 1 described above.
When assembling the downspout support 1A, first, the mounting surface 40a of the base 40 of the mounting member 2 is brought into contact with a predetermined position of the outer wall W as shown in FIG. Next, the screw shaft 28 of the fixing member 4 </ b> A is screwed into the through hole H of the mounting member 2, and one end 28 a of the screw shaft 28 is inserted until the other end 28 b of the screw shaft 28 is locked by the fitting protrusion 20. Let it penetrate the outer wall W. By this step, the mounting member 2 and the fixing member 4A are fixed to the outer wall W with the fixing member 4A penetrating the mounting member 2. Further, the outer peripheral surface 28R of the other end 28b of the fixing member 4A and the convex curved surface 34 of the mounting member 2 are connected without a step, and form a spherical surface as a whole. That is, the fitting projection 20 of the mounting member 2 and the other end 28b of the fixing member 4A integrally form a sphere.

  Next, the fitting cylindrical portion 36 of the downspout holding member 10A is elastically deformed as appropriate, and spherically fitted to the fitting convex portion 20 of the mounting member 2 and the other end 28b of the fixing member 4A. The gutter T may be inserted into the band 11 of the gutter holding member 10A before the spherical fitting, and may be inserted into the band 11 of the gutter holding member 10A after the spherical fitting. You may.

As described above, according to the downspout support 1 to which the present invention is applied, the screw shaft 28 of the fixing member 4 is provided on the fitting projection 20, the shaft 42, and the base 40 of the mounting member 2. One end 28a of the screw shaft 28 of the fixing member 4 is fixed to the outer wall W through the hole H. That is, the mounting member 2 and the fixing member 4 are integrally and reliably fixed to the outer wall W. Further, the screw shaft 28 of the fixing member 4 is inserted as a core into the mounting member 2 which forms a connection portion between the downspout holding member 10 and the outer wall W. That is, the connecting portion between the downspout holding member 10 and the outer wall W has a two-layer structure of the fixing member 4 and the mounting member 2 covering the outer periphery thereof. Therefore, the strength of the connecting portion between the downspout holding member 10 and the outer wall W can be increased.
Further, the fitting convex portion 20 having the second spherical portion 22 is spherically fitted to the fitting cylindrical portion 36 having the first spherical portion 14 so that the first spherical portion 14 abuts on the second spherical portion 22. The gutter holding member 10 is movable on the second spherical portion 22, and is supported rotatably with respect to the mounting member 2. In addition, since the gap S is formed in a portion where the first spherical portion 14 and the second spherical portion 22 do not come into contact with each other, the gutter holding member 10 does not buffer with the fixing member 4 when rotating. Therefore, the movable range of the downspout holding member 10 is sufficiently ensured.

As described above, the movable range of the gutter holding member 10 is sufficiently ensured, and the strength of the connecting portion between the gutter holding member 10 and the outer wall W is increased by the two-layer structure of the mounting member 2 and the fixing member 4. It is possible to provide a downspout support 1A that can widely cope with vibration of the downspout T due to wind or the like, and inclination or deformation of the outer wall W.
Further, since the mounting member 2 and the fixing member 4 can be integrally fixed to the outer wall W, the downspout support 1 can be downsized.
Furthermore, since the fixing member 4 is not visually recognized from the outside when the assembly is completed, the fixing member 4 is hardly affected by rain, wind, and the like, and the deterioration of the fixing member 4 can be prevented. And the beauty of the downspout support 1 can also be improved.

  The downspout support 1A according to the first embodiment has the functions and effects of the downspout support 1 described above. In addition, according to the gutter support 1A, the gutter holding member 10A has the fitting cylinder portion 36, and the spherical seat 38 formed on the inner surface of the fitting cylinder portion 36 is spherically fitted to the convex curved surface 34. Therefore, the fitting cylindrical portion 36 can move within a range in which the spherical seat 38 can abut on the convex curved surface 34, that is, while being in contact with the convex curved surface 34 other than the portion connected to the shaft 42. Therefore, the movable range of the downspout holding member 10A can be sufficiently secured.

  According to the downspout support 1A of the first embodiment, the outer peripheral surface 28R of the other end 28b of the fixing member 4A and the convex curved surface 34 of the fitting convex portion 20 of the mounting member 2 form a spherical surface. The joint tube portion 36 has a substantially omnidirectional orientation as long as the spherical seat 38 can contact the spherical surface of the outer peripheral surface 28R and the convex curved surface 34, that is, the spherical surface other than the connecting portion of the mounting member 2 with the shaft 42. , And can be moved smoothly. Therefore, the movable range of the downspout holding member 10A can be more sufficiently secured.

  In the gutter support 1A of the first embodiment, a part of the band 11 in the circumferential direction is cut in the axial direction (not shown) of the gutter T, and the band 11 can be butterflyed with the cut position as a base point. (Not shown). According to such a configuration, when assembling the gutter support 1A, the band portion 11 is opened in the radial direction by the hinge portion, and the gutter T is inserted into the hollow portion of the band portion 11 from the slit formed thereby. Can be inserted. After inserting the downspout T, the band portion 11 may be closed in the radial direction by the hinge portion, and the closed state of the band portion 11 may be maintained by some locking means or the like. This operation may be performed before and after the fitting cylindrical portion 36 of the downspout holding member 10A is spherically fitted to the fitting projection 20 of the mounting member 2 and the other end 28b of the fixing member 4A.

  Further, in the downspout support 1A of the first embodiment, the band portion 11 may be formed in a top-end tubular shape or a bottomed tubular shape. That is, the band portion 11 may be a socket into which the end of the downspout T can be inserted. According to such a configuration, when assembling the downspout support 1A, the upper end of the downspout T is fitted inside the top-end tubular band 11 or the downspout T is attached to the bottomed tubular band 11. Can be fitted inside. When such a configuration is adopted, a hole (not shown) for introducing rainwater into the cavity of the downspout T or discharging the rainwater from the cavity of the downspout T is provided in a part of the downspout T. Preferably, it is provided.

  The fixing member 4B of the downspout support 1B has a screw shaft 28, similarly to the fixing member 4A of the downspout support 1A. The width of the other end 28b of the screw shaft 28 is also enlarged, and the other end 28b is disposed in the gap S and is locked by the fitting projection 20. However, in the second embodiment, the width dimension of the other end 28b of the screw shaft 28 is smaller than the distal end surface of the fitting projection 20, and the outer peripheral surface 28R of the other end 28b of the fixing member 4B and the convex curved surface 34 are continuous. Not.

  When assembling the downspout support 1B, the same steps as those of the downspout support 1A described above may be performed.

The downspout support 1B of the second embodiment described above has the operational effects of the downspout support 1 described above.
In addition, also in the downspout support 1B, the downspout holding member 10A has the fitting tube portion 36, and the spherical seat 38 is spherically fitted to the convex curved surface 34. Therefore, the fitting tube portion 36 has the spherical seat 38. It is possible to move as long as it can contact the convex curved surface 34, that is, while contacting the convex curved surface 34 other than the portion connected to the shaft 42. Therefore, the movable range of the downspout holding member 10A can be sufficiently secured.
As described above, if the movable range of the downspout holding member 10A is sufficiently ensured, and the other end 28b of the fixing member 4 is arranged in the gap S and does not buffer during rotation of the downspout holding member 10A, the other end 28b Can be arbitrarily changed, so that a general fixing member such as a screw can be applied to the downspout support 1B. Further, the degree of freedom of design, versatility, etc. of the downspout support 1B can be expanded.

(Third embodiment)
Next, a downspout support 1C of a third embodiment (hereinafter, simply referred to as a third embodiment) to which the present invention is applied will be described.
FIG. 4 is a sectional view showing the downspout support 1C. In the components of the downspout support 1C shown in FIG. 4, the same components as those of the downspout support 1A shown in FIG. 1 are denoted by the same reference numerals, and the description thereof will be omitted.

In the third embodiment, as shown in FIG. 4, the downspout T has a tubular body 62 and a mounting rib 63. The mounting rib 63 protrudes from the outer peripheral surface of the tubular body 62 radially outward of the tubular body 62 and extends in the axial direction of the tubular body 62.
The mounting rib 63 is formed in a substantially T shape in a cross-sectional view orthogonal to the axial direction of the cylindrical body 62, and includes a shaft portion 56 and a locking portion 65. The shaft portion 56 protrudes radially outward from the outer peripheral surface of the tubular body 62. The locking portions 65 are formed so as to protrude from the tip of the shaft portion 56 in the protruding direction (ie, the gutter support axis O direction) to both sides (ie, radially outward) in a direction orthogonal to the protruding direction. I have. A groove 61 surrounded by the cylindrical body 62, the shaft 56 and the locking portion 65 is formed in the downspout T.
The mounting rib 63 only needs to protrude radially outward of the cylindrical body 62 from the outer peripheral surface of the cylindrical body 62, and may have a shape other than the above.

Regarding the downspout support 1C, the downspout holding member 10B is not provided with the band portion 11, but is provided with the fitting protruding portion 12, that is, the fitting tube portion 36, and the posture confirmation protruding portion 53.
A fitting groove 71 is formed in the base end 68 of the fitting cylinder 36. The fitting groove 71 extends in the vertical direction over the height of the fitting cylindrical portion 36 so that the mounting rib 63 can be fitted therein. The fitting groove 71 communicates with the gap S at the center of the height of the fitting cylinder 36.

A pair of mounting rib gripping portions 72 are provided on the base end portion 68 of the fitting tube portion 36 so as to sandwich the fitting groove 71 from both sides around the gutter support shaft O. The width of the mounting rib grips 72, 72 in the width direction is smaller than the width of the locking portion 65 of the mounting rib 63. Thus, the mounting ribs 63 can be inserted into the fitting grooves 71 by elastically deforming the mounting rib grips 72, 72 so that the mounting rib grips 72, 72 are separated from each other. At this time, the mounting rib gripping portions 72 can contact the cylindrical body 62 from the outer peripheral surface side.
The distal ends of the mounting rib grips 72 are bent toward the gap S. The locking piece 73 is constituted by the bent portion in this manner. The pair of locking pieces 73 can be brought into contact with the locking portion 65 when the mounting rib 63 is inserted into the fitting groove 71.
The inner peripheral side surface of the locking piece 73 is formed in a substantially arc shape in a cross-sectional view orthogonal to the axial direction of the cylindrical body 62. Therefore, when the locking portion 65 of the mounting rib 63 is pressed against the inner peripheral side surface, the mounting rib 63 is guided in the direction toward the gap S along the inner peripheral side surface of the locking piece 73.

The posture checking protrusion 53 is a member for facilitating checking the extending direction of the fitting groove 71 when fixing the downspout support 1C to the outer wall W. The posture checking protrusion 53 of the third embodiment is formed in a rod shape having a predetermined length protruding vertically upward and downward from the upper surface and the lower surface of the fitting tube portion 36, respectively. Note that the posture confirmation protrusion 53 is not limited to a rod shape and may be formed in a plate shape, for example, as long as it has the predetermined length.
On the outer wall W side of the fitting groove 71 of the fitting cylindrical portion 36, a pair of grip portions 74, 74 are provided so as to sandwich the posture checking protrusion 53 from both sides around the gutter support shaft O.

The downspout support 1C according to the third embodiment described above has the operational effects of the downspout support 1 described above.
Further, in the downspout support 1C, similarly to the downspout support 1A of the first embodiment, the fitting cylindrical portion 36 is in a range where the spherical seat 38 can contact the outer peripheral surface 28R and the convex curved surface 34, that is, the shaft. It is possible to move while abutting on the convex curved surface 34 and the outer peripheral surface 28R other than the portion connected to the body 42. Therefore, the movable range of the downspout holding member 10B and the downspout T connectable to the downspout holding member 10B can be sufficiently ensured.
FIGS. 5 and 6 are cross-sectional views each showing a part of the downspout support 1C attached to each of the outer walls V1 and V2. As shown in FIGS. 5 and 6, the outer walls V1 and V2 are different from the outer wall W and have different shapes. By the above-described operation and effect, the downspout support 1C corresponds to, for example, the outer walls V1 and V2, and is stably fixed. Further, it is possible to cope with a wall surface having a shape different from that of the outer walls W, V1, V2.

FIG. 7 is a perspective view for explaining a method of assembling the downspout support 1C shown in FIG.
When assembling the downspout support 1C, the same steps as the steps of assembling the downspout support 1A described above are performed until the mounting member 2 and the fixing member 4A are first fixed to the outer wall W.
Next, the posture confirming projection 53 is fitted into the gripping parts 74 of the fitting cylinder part 36. Then, the downspout T is carried to the vicinity of the downspout support 1C, and the mounting rib 63 of the downspout T and the fitting groove 71 of the fitting tube portion 36 are opposed to each other. At this time, in order to check whether or not the downspout T extends in the vertical direction, the posture confirmation protrusion 53 may be referred to as a reference in the vertical direction.
Subsequently, the downspout T is moved toward the fitting cylinder portion 36, and the locking portion 65 of the mounting rib 63 is pressed against the locking piece 73 of the mounting rib grip portion 72. Then, the locking portion 65 of the mounting rib 63 is pressed against the locking piece 73 of the mounting rib gripping portion 72 to elastically deform the pair of mounting rib gripping portions 72, 72 in a direction away from each other. Is inserted. Thereby, as shown in FIG. 7, the pair of mounting rib gripping portions 72, 72 sandwich the mounting rib 63. Further, the locking piece 73 of the mounting rib gripping portion 72 is inserted into the groove 61 of the downspout T, and the mounting rib 63 of the downspout T is mounted in the fitting groove 71 of the fitting tube 36.
Then, similarly to the process of assembling the downspout support 1A, the fitting tube 36 is elastically deformed as appropriate, and spherically fitted to the fitting projection 20 of the mounting member 2 and the other end 28b of the fixing member 4A. The mounting rib 63 of the downspout T may be fitted into the fitting groove 71 before performing the spherical fitting, or may be fitted into the fitting groove 71 after performing the spherical fitting.
